FIG. 3 is a schematic configuration diagram of main parts of a transfer section. The transfer paper fed from a feeding means (not shown) is transferred to a guide plate 5.
passage or guide plate 6a, 6 made by a, 5b
It is sent to the feed roller 9 through the path made in step b and is put on standby. Then, the transfer paper is timed to the position of the toner image formed on the photoreceptor 10, is moved to the transfer position by the feed roller 9, and the toner image is transferred. However, if the transfer paper is not conveyed smoothly and a paper jam occurs in the guide plate section or the like, it is not easy to remove the transfer paper. If a paper jam actually occurs in the guide plate section, use the limited space inside the machine to open the guide plates of the upper transfer paper path and the lower transfer paper path and remove the jammed transfer paper. In addition, even when the guide plate section is pulled out of the machine, it is common practice to pull the guide plate section out of the machine, check the guide plates of the two transfer paper paths in the same way, and remove any jammed transfer paper. ing.

The method of opening the guide plate inside the copying machine does not take up enough space, and the uppermost guide plate in particular hits the equipment above it, so it is difficult to open the guide plate enough to remove the jammed transfer paper. The board won't open.
In addition, even in models where the guide plate section can be pulled out of the copying machine main body, the structure is such that the guide plate on one side of each paper path can be rotated around a single point, but since there are multiple paper paths, the guide plate and guide The plates cross and it is not possible to fully open the transfer paper path. Therefore, if the transfer paper becomes jammed in the lower transfer paper path, the guide plate of the upper transfer paper path will get in the way, making it impossible to remove the jammed transfer paper easily, and even if it is impossible to remove it. Even if it is possible to do so, if a piece of the transfer paper remains inside the guide plate, it cannot be removed. Furthermore, multiple tasks are required, such as checking the upper transfer paper path and the lower transfer paper path, respectively. Furthermore, after opening the guide plate and removing the jammed transfer paper, the guide plate must be returned to its original position, and the next copy can be started without setting the guide plate to its original position. If you do so, it has the disadvantage of causing a paper jam again.
